MITRE ATT&CK
T1059.005 Visual Basic

The file is a legacy Word document containing WordBasic macros. The presence of the 'AuToClOsE' marker strongly suggests an auto-executing macro, a common technique for legacy malware to initiate malicious actions upon document opening. The ClamAV detection as 'Legacy.Trojan.Agent-443' further supports its malicious nature, although the specific family could not be determined.

Heuristics 2

  • ClamAV: Legacy.Trojan.Agent-443 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Legacy.Trojan.Agent-443
  • Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXEC
    OLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
